This is all i am doing, but this code is not working. plz help me out.

Your server code doesn't read the data the way it is sent by the
client.
You used a StreamWriter on the client end - why not use a
StreamReader on the server end? Regardless, you'll need to
parse the stream exactly the way it was sent. You receive
1024 bytes then try to receive the entire image, part of
which was already received in the first 1024 bytes - that's
not going to work. This is all assuming your Encoding.ASCII.GetString()
call works the way you expect, which I don't think does.
Also, is there a reason the client writes the Bitmap to disk
then reads it back as an Image? A Bitmap IS an Image (Bitmap
derives from Image).

you can do so ... but you need to know how the sockets are working ... and which implementation of you should use (Asyncrounous or Syncronous) ... eventually you will implement your own mechanism of file transfering as I have done before ... actually its kindda fun working with sockets

Hi,
I have a windows form with its Background Image property set to a .jpg which is in the Resources folder.
I want to be able to change the Background Image from the App.Config file.
I've set the properties needed in the App.Config file, and I've written a bit of code in the Form Load event, which points to the correct jpg. However, when I change the image in the config file, the form still loads the original image. Is there something I should be putting into the Form Load event to load the new jpg? I've tried refresh, but that doesn't work, the code I'm using is as follows:
private void FormDisplay_Load(object sender, EventArgs e)
{
try
{
........
CustomerDisplay.Properties.Settings mySettings = new CustomerDisplay.Properties.Settings();
Image Img = Image.FromFile(mySettings.BackgroundImage);
anyone have any ideas?
Thanks,
RB

Assume you have a resource folder with different possible background images, and your configuration file contains a user setting BackgroundImageFile which is of type string. The setting is to hold the filepath (e.g. \Resources\picture.jpg) of the actually desired background image. Then either you use property binding (see MSDN), or you bind the image yourself in the Load-Event-Handler:
private void Form1_Load(object sender, EventArgs e)
{
try
{
this.BackgroundImage = Image.FromFile(Properties.Settings.Default.BackgroundImageFile);
}
catch (Exception ex)
{
}
}
You don't need to instantiate a new object of the settings class unless you implemented your own.

I am programming in C# using Visual Studio 2008 on Windows XP.
I have a TTS application that is working fine using the SpVoice class (from SpeechLib) to speak text. However, I only have a few voices to choose from... Microsoft Mike, Sam, and Mary. That's all I have access to, and I really need a few more voices. So, I have two basic questions:
1) Where can I get additional voices to use in my app? I want something like the three listed above, which seem to work no matter what the word is.
2) Is there a way for me to create new voices that I can use, complete voices like Microsoft Sam and family?

|

the interweb has tones of them...i recomend the HomeSeer voices i think they're Kate and Paul, i think you could create your own voices, but i imagine it would be very very difficult.

I am looking for a third part control to run a series of virtual camera's so I can analysis a series of pre-recorded video streams simultaneously. I have downloaded several virtual web cam products, some of which work well for single camera simulation and have send E-mail inquiries on purchasing a control but have only gotten back bounced e-mail messages or nothing at all.
Can anyone point me to a control for sale or even better, free?

I can imagine you are getting frustrated with this effort, but dude, really, this is a C# question?

how to fixed a mdi child form on restricted ares ... i must be move only small areas only
do you know pls reply me
laknath

It can be done by checking the location property of the form in the move or locationchanged event but it's nasty as the form jumps.
I wrote an article[^] about doing this with dialog forms (not children) but you may be able to adapt it.
The trick is to capture the WM_NCLBUTTONDOWN message that occurs when the title bar of the form is clicked and calculate the rectangle from that cursor point where movement is allowed - and set the cursor's clip property to that rectangle. You need to remove the clip after the mouse is released

How do I link a keyboard shortcut to a button on a form? I have added shortcuts to menu items-that is very straightforward-but for some reason, I cannot find information on how to add the shortcut to a button.
Thanks.
|
|

|

just use Amperion ("&") before the charecter on which you want to use Keyboard Shortcut.
<br />
e.g : Button Text="Click"<br />
<br />
Just Give "&Click"
and on Runtime -> "Alt + C" will invoked Button Click Methods !!!!

Is there a symbol that can be used for Ctrl + C instead of Alt + C?

Abhijit's answer is correct. if you want to assign function keys, you'll have to set the Form's KeyPreview property to true and handle the Form's KeyPress or KeyDown events and call the PerformClick method (and Focus if you need it) of the button you want pressed.
